But Yvonne remained firm she would only accept Chris and not his long-term partner and now husband, Grant.

"I wouldn't allow him to come back with his husband. I don't want his lifestyle in my home," she said.

Yvonne remained adamant this didn't mean she had disowned him.

"My husband has made contact with him. We haven't disowned him," she said.

"I have been a Jehovah's Witness since I was 19."

Chris declined to comment on his mum's views.

In an exclusive interview with the Daily in March, Yvonne explained why she refused to attend her son's wedding.

She said her decision to not go was because "I believe homosexuality is wrong".

"I am one of the Jehovah's Witnesses by my own free will and I hold very dearly the value and principles in the Bible."

Yvonne said she didn't "hate homosexuals, that's not my place".

"As a Christian, it is not my place to hate anyone, but that doesn't mean I have to accept other people's lifestyle choices.

"I have held these beliefs since I was 19."

Yvonne's determination to reject her son's relationship comes as ex-Jehovah's Witnesses around the world prepare to mark their annual Watchtower Victims Memorial Day, which is "a worldwide day of mourning and respect for all victims of the hurtful and hateful policies of the Watchtower Bible and Tract Society, commonly known as Jehovah's Witnesses" on July 26.

A number of victims were planning a memorial outside the Melbourne Magistrates Court where Cardinal George Pell will face the court for a filing hearing on sexual abuse charges.

Lara Kaput, who planned to attend the Melbourne memorial, said she had left the Jehovah's Witness church 25 years ago and did not have contact with her family.

"My family, who are generally Jehovah's Witness, don't speak to me," she said.

"I'm being shunned, same as Chris is by his mother, except it is because I left the religion.

"I didn't like the high control environment and I didn't like that women couldn't be in leadership and I didn't believe in it.

"A group of us are meeting at Melbourne Magistrates Court to speak about Watchtower Victim's Memorial Day."

Ms Kaput said Chris had joined a secret victims support Facebook group she was part of and he had been offered help.
